where <N> is an
integer between one and the number of processor threads, inclusive.
In order to investigate a particular apparently failing test, e.g
“test-parse-date.t”, issue
the following commands (notice that omitting --debug sometimes modifies the result):

If you built the documentation, install it by running the following
command (as root):

make PREFIX=/usr install-doc

After installed, two very quick and simple tests should run
correctly. First one needs some configuration:

cat >> ~/.hgrc << "EOF"
[ui]
username = <user_name> <your@mail>
EOF

where you must replace <user_name> and <your@mail>
(mail is optional and can be omitted). With the user identity
defined, run hg
debuginstall and several lines will be displayed,
the last one reading "no problems detected". Another quick and
simple test is just hg, which should output basic
commands that can be used with hg.
